NAME

       Table - read and write ASCII and FITS tables

SYNOPSIS

       asttable [OPTION...] ASTRdata

DESCRIPTION

       Table is part of GNU Astronomy Utilities 0.19.  Table can be used to view the information,
       select columns, or convert tables.  The  inputs  and  outputs  can  be  plain  text  (with
       white-space or comma as delimiters), FITS ascii, or FITS binary tables. The output columns
       can either be selected by number (counting from 1), name or using regular expressions. For
       regular expressions, enclose the value to the '--column' ('-c') option in slashes ('\', as
       in '-c\^mag\'). To print the selected columns on the command-line, don't specify an output
       file.

       For  more  information, please run any of the following commands. In particular the second
       contains a very  comprehensive  explanation  of  Table's  invocation:  expected  input(s),
       output(s), and a full description of all the options.

       All options and their values:
              $ asttable -P

       Inputs/Outputs and options:
              $ info asttable

       Full section in manual/book:
              $ info Table

       Full Gnuastro manual/book:
              $ info gnuastro

       Gnuastro users and developers. For more information, please run:
